Hello, I created a function to validate cnpj in my form and I need to use a focus () for the cursor to stay in the input when the user enters the wrong cnpj, but there are 3 different fields of cnpj. I have done it in several ways, but he only accepts in the first field.

jquery:

jQuery.fn.validacnpj = function () {
this.change(function () {
    CNPJ = $(this).val();
    if (!CNPJ) {
        return false;
    }
    erro = new String;
    if (CNPJ == "00.000.000/0000-00") {
        erro += "CNPJ inválido\n\n";
    }
    CNPJ = CNPJ.replace(".", "");
    CNPJ = CNPJ.replace(".", "");
    CNPJ = CNPJ.replace("-", "");
    CNPJ = CNPJ.replace("/", "");

    var a = [];
    var b = new Number;
    var c = [6, 5, 4, 3, 2, 9, 8, 7, 6, 5, 4, 3, 2];
    for (i = 0; i < 12; i++) {
        a[i] = CNPJ.charAt(i);
        b += a[i] * c[i + 1];
    }
    if ((x = b % 11) < 2) {
        a[12] = 0
    } else {
        a[12] = 11 - x
    }
    b = 0;
    for (y = 0; y < 13; y++) {
        b += (a[y] * c[y]);
    }
    if ((x = b % 11) < 2) {
        a[13] = 0;
    } else {
        a[13] = 11 - x;
    }
    if ((CNPJ.charAt(12) != a[12]) || (CNPJ.charAt(13) != a[13])) {
        erro += "Dígito verificador com problema!";
    }
    if (erro.length > 0) {
        $(this).val('');
        alert(erro);
        $(document).ready(function () {
            $("#cnpj").focus();
        });

        setTimeout(function () {
            $(this).focus()
        }, 100);
    }
    return $(this);
});

};

Read word file in laravel 5.3 jQuery Ajax generating image error

score 1 · Answer 1

Some remarks about your code:

Using document.ready in the wrong location: this will not run inside your code block:

if (erro.length > 0) {
    $(this).val('');
    alert(erro);
    $(document).ready(function () {
        $("#cnpj").focus();
    });    // resto do código omitido

The event "ready" is from the document and will not be impacted by its if .

Two focus: you are first using a $("#cnpj").focus(); , which will clearly position the focus on the element with id "cnpj", regardless of who is wrong, the correct one, since you are validating the input itself would be $(this).focus() only.
Escope of this : each function has its own scope, and probably this within function with setTimeout is not the same, so this does not mean the same object. Try to associate this with a variable, like this:
```
alert(erro);
var elem = $(this);
setTimeout(function () { elem.focus(); }, 100); 
```

I think this will solve your problem.
